Coal furnace keeps shuting down over night and going out. Hit reset button and the blower and auger start back up but of course I have to relight. If i lower the blower speed it seems like the coal does not burn all the way. Auger is set on two right now. Hard to figure out the perfect setting.

Yep it runs if I close that relay. So I get it started it will run for awhile. Then in the morning or after a couple hours I will go down and the motor will have a slight hum buzz push that red button and it start up.

so I messed with the timer a lot and got it to run 10 on 18 off it ran all night in the morning the house was 73 degrees at the thermostat. so i waited for it to time out and shut down. Then ran the t stat up passed 73 did not come on strange because it was runninig with the t sat last week. T stat is digital and new. I think the moter is ok, but your right it is old.
